I need some help from you Yamaha guys. I have been riding a Cat for years so I don't know much about a Apex but I know this form does. I'm considering buying turbo Apex 2007 se built by LCC in WY. The machine has only 200 miles on it is like new. My question is on the turbo it's a Rock and Roll turbo are they good or bad. Thanks maybe x Arctic Cat rider.
